Two portraits of Agrippa Postumus in the British Museum

Two damaged and partially restored Roman portraits in the collection of the British Museum, previously identified as being either the emperor Caligula or an unknown “JulioClaudian prince,” are here reassessed and identified as Agrippa Postumus, the youngest grandson and adopted heir of Augustus. The first portrait, from southern Britain, may have come from a temple dedicated to the worship of the Julio-Claudian house, while the second was probably part of an equestrian group standing outside the Aedes Castoris in Rome. This is a significant reinterpretation, providing potential evidence not only for links between Rome’s first family and the rulers of a distant client kingdom, but also for the framing of imperial power and the uncertain nature of the Augustan succession in the early years of the 1st c.
